lNKlNG-RIBBON SPOOL FOR TYPE-WRITING MACHINES.

SPECIFICATION forming part of Letters Patent N0. 401,856, dated April23, 1889.

Application filed June 8, 1887 $erial No. 240,632. (N0 model.)

To all whom it may concern:

Be it known that I, HARVEY RAY, of Mobile, in the county of Mobile andState of Alabama, have invented new and useful Improvements in InkingRibbon Spools for Type-\Vriting Machines, of which the follow ing is afull, clear, and exact description.

My invention relates to inking ribbon spools for typewriting machines,and has for its object to provide simple inexpensive spools of thischaracter, which will allow separate manufacture and transportation ofthe inking-ribbons by mail or otherwise, and in such manner that theribbons may be very quickly and easily adj usted to the type-writer andallowinterchange of a series of inkingribbons of various colors with buta single set of ribbon-spools fitted to the machine.

The invention will first be particularly described, and then pointed outin the claims.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which- Figure 1 is an edge view of my improvedinking-ribbon spool with a small piece of the ribbon held on the bobbinof the spool. Fig. 2 is an inside face view of one side part of thespool with the bobbin on the hub and a part of the inking-ribbonattached. Fig. 3 is an inside face view of the other part of theribbon-spool. Fig. 4 is a perspective view of the bobbin with a portionof the attached inking-ribbon; and Fig. 5 is a central transversesection through. the spool.

One side, A, of the 1lblJ0]l-SpOOl is shown provided with peripheralteeth a, with which mechanism of the typewriter engages for turning thespool to carry a new or fresh part of the inking'ribbon to the point ofi1npression of the type; but the spool may receive motion for thispurpose in. any approved way. On the side of A is fixed a hub, B, whichis slotted lengthwise at b to receive an inwardly-bent tongue, 0, of theinking-ribbon bobbin C, which consists of a plate of metal or othersuitable material bent around from its tongue 0 to fit loosely upon thehub B, and at its other end. part is bent upon itself to form a clamp,0, into which the end of the inking-ribbon l) is fastened, as shown mostclearly in Figs. 2 and. at of the drawings. The other side part, E, ofthe spool is provided with a hub, F, which fits snugly inside of the hubB of the side A, and against the end of the bobbin, as will beunderstood from Figs. 1 and 5 of the drawings. The side plates, A E,thus form walls, between which the inking-ribbon will be held trulyedgewise. The ribbon D will be wound upon the bobbin G and upon itself,and may have any required length up to the full capacity of the spool.

It is obvious that by removing the side portion, E F, from the oppositeside part, A B, the bobbin with the ribbon wound 011 it may be slippedfrom the hub B of side A and another bobbin carrying a fresh ribbon ofthe same color or of a different color may be quickly placed on the hubB and the side E F readjusted, and when. the free end of the ribbon issecured to an opposite spool the type-writer is ready for operation;hence the advantages of the spool are evident,'as ink ing-ribbons may bequickly and easily substituted, one for the other, without soiling thefingers, and two or more different colorsof inking-ribbon can be used onthe same spool, thus allowing a variety of inking-ribbons to be usedinterchangeably on the type-writer with but one set of spools, and theribbons wound on the bobbins can be furnished by the manufacturer atlittle expense, and they may be sent by mail. or otherwise at a triflingcost, thereby promoting the economical maintonance of the typeavritingmachine in good order for a wide range of wor c.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is-

1. An inkinguibbOn bobbin provided with a clamp on its outer surface,and with an inwardly-extending projection on its inner surface,substantially as described.

2. The inking-ribbon bobbin C, formed of a plate bent into cylindricalform an d provided at one end with an inbent lip, c, and at the otherend with a ribbon-clamp, c, substantially as shown and described.

3. The inking-ribbon bobbin 0, provided at one end with an inbent lip,c,and at its other end with a clamp, 0', combined with an inking-ribbon,D, held at one end by the clamp c, and wound upon the bobbin,substantially as herein set forth.

4:. The combination, in an inking-ribbon spool for a type-writer, of aside part, A, having a hub, B, slotted at b, a bobbin, 0, fitted to saidhub and having a tongue, 0, entering said slot and adapted to hold theend of the inking-ribbon, and an opposite side part, E,

having a hub, F, fitting the hub B of part A, 10

substantially as described, for the purposes set forth.

HARVEY RAY.
